The power and thrust of Boeing's 757 just all around rocks. Now, I've been on 757s aboard UA, AA, NW, and BA. Is it my imagination, or does some takeoff thrusts seem more powerful aboard certain carriers than others? (These were takeoffs from normal-length runways in good weather; not from the ridiculously short ones like LGA, SNA, or DCA.)
If there truly IS a difference, I was wondering if it was because of engine types. Is Pratt & Whitney more powerful than GE? Or is Rolls Royce more powerful than either. Are they about the same performance-wise? -I know BA uses Rolls Royce, and I think UA uses GE (I might be wrong on that one). It seems like the NW 757s take off with more power than UA and AA. Is it because they use Pratt & Whitney?
Or could it had just been what I was smokin' before the flight?

United uses Pratt & Whitney, as does Northwest, TWA, and Delta. Continental, USAirways, ATA, American and America West use Rolls Royce.
UPS uses both powerplants on their 757 freighter fleet.

Only two powerplants are offered to the 757s. Either a PW or a RR. They shouldn't be any noticeable differences among them but NW birds do operate at the lowest MTOW of all US registered 757s.
